UNITED STATES PATENT OFFICEe JOHN A. SWANSON AND AUGUST W. LINTON, OF FARGO, DAKOTA TERRITORY.

MACHINE FOR MAKING BRICK FROM DRY MATERIAL.

SPECIFICATION forming part of Letters Patent No. 348,702, dated September 7,1886.

Application filed March 4, 1886.

To all whom it may concern.-

Be it know that we, JOHN A. Swanson and AUGUST W. LINTON, citizens of the United States, residing at Fargo, in the county of Cass, Dakota Territory, have invented certain new and useful Improvements in Machines for Making Brick from Dry Material; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form apart of this specification.

Our brick-press is designed for pressing brick from dry pulverized material, so that as fast as the bricks are pressed and dropped out of the molds they may at once be burned.

In the accompanying drawings, Figure 1 is a side elevation of our brick-press, part of it being in section and a part of it, deemed unnecessary to be shown, broken away. Figs. 2, 3, and 4 are detail views of the same.

Our invention is described as follows:

Referring to the drawings, Fig. 1, A A A A represent the parts of the frame wherein the machinery proper is mounted. A and A are made in pairs; but to more plainly show the working of the machine the front pair is removed. The power for operating the machine is applied by means of a belt working on a pulley-wheel, B, and through said pulley and a double'set of gearing, B, it is communicated toa crank, O, pitman D, balance E, and thrust-bar F, to the reciprocator G. Reciprocator G is pivoted on a strong journal or pin, H, and the lower reciprocator, I, is pivoted on another strong journal, H. Thus by a continuous motion of the gearing B the reciprocator G obtains a rocking motion, which it imparts to the lower reciprocator, I, through the sliding block J. It will be seen that the dies K and L, which move perpendicularly in the guides M and N, and connected to reciprocators G and I by means of sliding blocks 0 and P, will at one oscillation of the reciprocators, move toward each other, and at the return oscillation move away from each other.

Q is the molding-table, containing eight brick-molds, R. This molding-table is mountedon a shaft, S, journaled in a bearing, S and step S There is also keyed on shaft S, afourtoothed ratchet-wheel, S forthe purpose of turning the molding-table Q ninety degrees to every reciprocation of the dies. This turning of the table is accomplished by means of a ratchet-bar, S and a knee-lever, S actuated by lever E by means of a bar, S", pivoted to the short end Eof the said lever E and to the lower end of the knee-lever S said ratchetbar being hollowed out to work over the said ratchet-wheel S I T is part of a stationary segment,which, at

the place where the dies enter, is provided with holes T, corresponding with the brickmolds R. Now, as the pulverized material is conveyed by the conveyer U it drops into the two molds R at that place and on top of the segment T,

and is carried by the mold-board Q ninety de- I grees to the right, where the two dies K and L will by that time be ready to press the pulverized material to the proper size of a brick.

After the bricks are pressed they follow the 7 5 table or mold-board to a point diametrically opposite to where they are pressed, and are then pushed out of the molds by means of the walking-beam V, pitman V, and

plunger V, and conveyed to the desired 8o thereby pushing the rod WV? through the slide- 90 block- W, and thrusts the bar F olffrom the end E of the lever E, and by so doing the reciprocators and everything connected with them is left to the action of a strong spring,

X, which quickly effects the return-stroke. 5

As the lever E is nearing its highest point, the spiral spring \V on rod W brings thrust-bar F in the proper position on the upper edge of the end E of the lever E. The spring X has its large end bolted to the frame A, while its me spring end is pivoted to the lower end of a rod, X whose upper end is pivoted to the arm X of the reciprocator I. If we wish to Stop the press and mold-table, we pull hand? In order to lever Y over a knob, Y, on the segment Y, thereby disengaging thrust-bar F,by means of r the rod Y, from contact with the mainpressboard are at rest.

In Fig. 4 is shown an inverted view of the mold-table, showing the segment T covering two of the holes or molds B. These two molds covered are the ones being filled by thesconveyer U. This segment T is stationary, while the mold-table Q moves over it.

This machine is made adjustable wherever necessary.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The combination, with the frame A A A A, pulley B, double gearing B, and crank O, of pitman D, its upper end pivoted on the arm of crank 0, its lower end pivoted to the long arm of the balance E, balance E, fulcrumed on the lower part of said frame, thrustbar F, its lower end working on the short arm E of the balance E, its upper end pivoted to the outer arm of the reciprocator G, reciprocators G and I, pivoted to the said frame by journals H and H, and pivoted together by sliding block J, dies K and L, pivoted to the inner arms of the said reciprocators by means of sliding blocks 0 and P, and working up and down in the guides M and N, substantially "as shown and described.

2.
